Question

y=x²-3x-4 put
x=-2
x=-1
x=1 ​

Answer 1

Step-by-step explanation:

To solve: x2 + 3x – 4 = 0 subtract x2 + 3x – 4 = 0 from y = x2 + 3x – 4,

The points of intersection of the parabola with the x axis are the points (-4, 0) and (1, 0), whose x – coordinates (-4, 1) is the solution, set for the equation x2 + 3x – 4 = 0.
